The leading U.S. infectious disease expert says he is "cautiously optimistic" that a coronavirus vaccine with some degree of effectiveness will be successfully developed by the end of the year or the beginning of 2021.
According to the AP, Dr. Anthony Fauci told a U.N. event Wednesday that Moderna's vaccine will go into Phase 3 trials "sometime at the end of July and then others will follow in August, September and October."
He said Moderna's vaccine has shown "very promising" results, but added "you could never, ever predict with any certainty whether a vaccine is going to be safe and effective."
He also said a "strategic approach" had been adopted to test multiple vaccine candidates using the same standards and measurements.
Fauci heads the National Institute of Allergy and Infectious Diseases.
